clam
 

I would buy some live clams, open them up and throw the shell and clam meat into the tank. They will usually land right side up and the butterflies should go crazy for this food.The left over clams i would freeze and when its time to feed, slip a sharp knife into between the frozen shell and cut straight through. it will open the clam and cut the meat into two for feeding.

Can you post a pic?

The four fish you bought are doomed
see http://wetwebmedia.com/poorchaetodons.htm

Carefully immediately remove them from your tank and return them to the LFS that ou bought them from and get your money back and give them an earfull as well as they will die in his tank.

I say so politely, but please, in the future never buy a fish unless you have throughly studied their needs and ask questions before you buy.

Interesting list, how come I didn't know (before I got one) that clown tangs are listed as "class A" never to be kept in captivity. *Sigh* the things you learn after the fact :sad:

Good luck with your butterfly fish, I hope they make it. Did you try feeding clam, if you did how did it go?

Though it is nice to see a the list, they are still in the business of selling fish.
www.wetwebmedia.com has a better list.
They list good and bad of most of the species and should be a must read a reefer buys a fish.

Thanks
